Summary: I mostly use it (via Novoflex adapter) on an OM-D now, where it acts the 1:1, 110mm equivalent. On full frame : sharpness wide open is good, but it has less contrast than recent 50mm lenses, especially when bright lights are in the frame.
Excerpt: I have owned one of these in one form or another since about 1969 and would not be without it. My wife also uses one as her all-around lens. Focusing is easy, even in low light. Speed is adequate for general use. Small size makes it easy to carry. Image quality is great.
Summary: I love this lens. This is one of the first good Nikkor lenses I bought back in the '90s and I still have it and use it every day. Although I use it on F, F2, FM and F4s bodies, I mainly use it on a Sony NEX-7 and NEX-5.
Summary: Purchased second hand. Manual focus. Crisp images. Pleasing background blurring at wider apertures. At narrow apertures, the 7 blades are readily apparent on blurred circular highlights. There might be some scratches on the glass. I'll need to shoot more at various apertures with bland background.
Excerpt: I was able to take a few shots with this lens before I had to return it. The sharpness and micro detail for this focal length was astounding. For some reason the aperture could not be adjusted from the camera. I bought it for this reason since I already own a 55mm 3.5 micro AI.
